DataDistiller™ is an independent engine which does not require Microsoft Office®
or any other application to be installed in order to remove metadata / hidden data.
DataDistiller™ Engine is able to remove metadata / hidden data from the following
file formats:

Microsoft® Word Documents

Microsoft Excel® Workbooks

Microsoft PowerPoint® Presentations

OpenDocument Text Documents

OpenDocument Spreadsheets

OpenDocument Presentations

OpenDocument Graphics

PDF Documents

JPEG Images

JPEG 2000 Images

PNG Images

SVG Images

AVI Video Files

MP3 Audio Files

MP4 Files

F4V Files

WAVE / BWF Audio Files

AIFF Audio Files

3GP Files

XML/XSD/XSL Files

DataDistiller™ Engine is able to remove metadata / hidden data of the following
types:

Document Properties

Document properties are Metadata that includes details such as author name, title,
subject, keywords, category, status, comments, revision number, and total editing
time. Document properties may also include user defined custom properties, a non-standard
metadata that can be added to a document.

Tracked Changes

Tracked changes are changes made to the document while the Track Changes option
was enabled. This include inserted, deleted, modified, and moved text. Every change
is saved with the name of the user who made the change, as well as the date and
time in which the change occurred. If the tracked changes are not removed from the
document, previous versions of the document can still be viewed.

Hidden Slides

Hidden slides are slides that were marked as hidden are not presented in the slide show.

Off-Slide Content

Microsoft PowerPoint® Presentations.

Off-Slide Content are content that have been placed outside the slide area and is not presented in the slide show.

PDF Metadata

Applicable to PDF documents.

PDF documents typically contain document information and XMP metadata. In addition,
due to performance considerations, deleted objects are sometimes left in the file
and only marked as deleted. Although this makes them invisible when viewed in a
standard PDF reader, it is still possible to retrieved them from the file.

There are several versions of PDF files. Currently, DataDistiller™ Engine can remove
hidden data from some of the PDF versions, which are the most commonly used.

JPEG metadata are added automatically by digital cameras, scanners, and image processing
software. This metadata often contains information such as the exact date and time
the photograph was taken, the digital camera manufacturer, model, and unique serial
number, the camera settings, and the location (if GPS-enabled camera was used).
Furthermore, a thumbnail of the image often exist in the JPEG file, and many image
manipulation software fail to update this thumbnail when the original image is modified.
So even if the image was cropped, or otherwise modified to hide certain parts in
it, the removed parts may still be visible in the thumbnail.

DataDistiller™ Engine can remove metadata from JPEG files without degrading the
image quality.

JPEG 2000 Metadata

Applicable to JPEG 2000 images.

JPEG 2000 metadata can contain various details about the file author, the software
used in its creation, and the time and date in which it was created. The metadata
can also be structured in XMP format.

PNG Metadata

Applicable to PNG images.

PNG metadata can contain various details about the image, such as the author, the
editing software, and the time and date in which it was created. The metadata can
also be structured within XMP (Extensible Metadata Platform).

DataDistiller™ Engine can remove metadata from PNG files without degrading the image
quality.

WAVE / BWF Metadata

Applicable to WAVE / Broadcast Wave Format audio files.

The metadata of WAVE / Broadcast Wave Format (BWF) files can contain various details
about the audio files, such as the author, the software used, and the time and date
in which they were created. The metadata can be structured in INFO, EXIF, XMP,
iXML, axml, Broadcast Audio Extension (Bext), ID3, and Cart chunk formats.
